METAL Disk WHEEL.

Application filed March 4, 1922. Serial No. 541,256.

. metal disk wheels, particularly for childrens vehicles.

It consists in the construction, arrangement and combination of parts as hereinafter particularly described and pointed out in the claims.

In the accompanying drawing like characters designate the same parts in the several 1 figures.

.Figure 1 is a side elevation of a wheel embodying the invention, portions of the rim, front web disk and hub cap being broken away; Fig. 2 isa cross section of the wheel on the line 22, Fig. 1;,Fig. 3 is a similar fragmentary section showing a rim of modified construction for a steel or metal tire; and Fig. 4 is a fragmentary face view of the construction shownin Fig. 3. Referring to Figs. 1 and 2', the wheel comprises two circular sheet metal disks or web 5 members 1, which are preferably symmetrically flared or bulged outwardly adjacent the center and to a less extent adjacent the rim, converging and then diverging from each other from the central portion towards 40 the rim of the wheel, as shown in Fig. 2.

The flaring shape of the disks braces the rim laterally, materially strengthens the wheel, provides a radially elastic and re: silient connection between the rim and hub which makes the wheel run smoother and increases its durability, and at the same time gives the wheel a.more substantial and attractive appearance.

The disks or web members are formed 5 around central circular openings therein with outwardly projecting'flanges 2 and 3. The flange 2 is formed with external capretaining lugs or projections 4.

A cylindrlcal hub-barrel 6, fitted at the ends in the flanged openings in the web disks'or members 1, is formed adjacent its ends with outwardly projecting stop. and spacing lugs 7, which engage with the inner sides of the disks 1 and properly space them from each other when the parts of the wheel are assembled with the flanges 2 and 3 flush with the ends of the barrel. The hub barrel 6 may be made of sheet metal tubing drawn seamless or shaped from a flat blank.

The wheel may be constructed fbr use with ball, roller or plain bearings.

When designed for use with ball bearings 9, as shown in Fig. 2, the hub barrel is formed with inwardly bent' or projecting stop lugs 10. and the bearings are fitted'in the ends of the barrel against the lugs 10, as shown in Fig. 2.

For roller bearings, the lugs 10 are omitted, and the hub may be-otherwise constructed for bearings of different kinds.

As shown in Fig. 2, the inner or one end of the hub is provided with a flanged bearing-retaining ring or dust guard 12, fitted over and secured on the flange 3 and extendmg inwardly over the edge of the flange and end of the barrel.

At the outer or other end the hub barrel is closed to exclude dust and dirt and to give a finished and attractive appearance to the wheel, by a sheet metal cap 14., fittingovr. the flange 2 and formed with an outwardly pressed annular bead or groove 15, or with internal recesses adapted to be sprung into and out of engagement with the lugs or projections 4.

The wheel is provided with a channelshaped sheet metal rim 17, having out and inturned marginal folds 18, which are clasped over and tightly embrace the peripheral edges of the disks or web members '1, and form'outwardly projecting tire-retaining flanges for confining a tire in the channel of the rim, such as a solid rubber tire 19, shown in Figs. 1 and 2. I

The two web disks formed and spaced from each other as shown, and secured at their edges in the marginal folds of the rim, brace each other and form a firm support for the rim and tire, admitting of the use of comparatively light gage sheet metal in the construction of the' wheel;

Referring to Figs. 3 and 4. showing a slight modification in the construction of the wardly beyond the flanges 18.

rim for steel or metal tires, the rim 17 like the rim 17 for rubber tires, is formed with marginal folds 18, which are claspedover the edges of the web disks or members 1.

Between the marginal folds and flanges 18 the rim is preferably crowned, as shown in Fig. 3, to fit into the concave side of a 'concavo-convex' steel or metal tire 1-9, the

In other respects the construction of the wheel for metal tires is the same as that for rubber tires. i

I claim: 7

1. A metal disk wheel comprising two sheet metal web members formed with outwardly flanged central openings, a hub barrel fitted in said flanged openings and formed with outwardly projecting stop and spacing lugs engaging the inner sides of the web members, and a sheet metal rim con-- necting the peripheries of the web members,

the distance between the web members at the hub barrel being greater than the dis tance between their peripheries at the rim.

2. A metal disk wheel comprising two sheet metal web members formed with central outwardly flanged openings, a hub barrel .fitted in said flanged openings and formed with outwardly and inwardly projecting lugs, the outwardly projecting lugs engaging the inner sides of the web members, ball bearings fitted in the ends of the hub barrel against its inwardly projecting lugs, a flanged ring fitted over and secured.

to the central web flange on one side of the wheel, and a cap removably fitted over the central web flange on the other side of the wheel. V

3. A metal disk wheel comprising two circular sheet metal web members formed with outwardly flanged central openings and bulged outwardly adjacent said openings and to a less extent adjacent their peripheries, the flange of one web member having anoutward projection, a sheet metal cap fitting over said flange and formed with a recess adapted'to be sprung into engagement with the projection on said flange, and a flanged ring fitted and secured on the flange of the other web member and extending inwardly over the outer end thereof.

In witness whereof'I hereto aflix my signature. v EDWARD R. WAGNER.
